Abstract
Apparatus for electronically modifying spark advance and dwell in a spark-ignited internal combustion engine. Conventional cam driven breaker points on the engine are initially set for the desired maximum spark advance. The signal from the breaker points is electronically delayed to reduce the spark advance by a predetermined constant value independent of the engine speed. Dwell is also electronically controlled to a predetermined constant value independent of the engine speed.
